COCCON Site Status Summary

Karlsruhe Fairbanks Gobabeb Thessaloniki
Kiruna Sondankylä Tsukuba Magurele
Seoul Jinja Harvard Forest Hyderabad

The tables below provide information on the operational status, the number of measurement days and the total number of measurements for each quarter per year and for the entire year at different sites. The number of measurement days for the whole year is given by two values. The first value refers to the measurement days before the application of additional filters (e.g. for the solar zenith angle) while the second value includes this filter. The additional value in parenthesis marked with an asterisk is therefore smaller than the first one. Especially in the winter months, depending on the location of the site, the solar zenith angles may be less than the selected filter threshold (i.e. less than 75°), so that the entire measurement day is not used for publication.
